HI,

I have added a Service provider and since i have down this a can’t get into call rules. It just comes up loading. I have tried in the following browsers and OS and i still get the problem.

Microsoft Windows XP Professional > Internet Explorer 7
Microsoft Windows XP Professional > FireFox
openSUSE 10.2 > Firefox
openSUSE 10.2 > Konqueror

Any ideas anyone?

Thanks
